Good for another 2 years

Can anyone recommend "progressive" bi-focals?
How about TRI-focals?

I use a bifocal in one eye, with the line lower than usual by a few mm.
That way I have one eye with full distant vision and at one eye that
can read an approach plate. IT took some getting used to (both eyes
could use bifocals) and the optician did not want to give me that kind
of prescription (even though the doctor said it was fine). He died a
week later and the new optician gave me the lenses I wanted.

Progressives have a blurry area right in the middle, and trifocals have
narrow areas of good focus. That would bug me.
